I've just scanned through AFPLectureNotes.pdf but it wasn't obvious to
me exactly how they worked, i.e. whether they calculated how long till
the first trigger or just stepped in discrete timesteps.

We also want consistent game speed on different computer speeds don't
forget.

Can yampa give us what we want?
